Description

【０００１】
【発明の属する技術分野】
本発明はベビーベッドに関するものである。
【０００２】
【従来の技術】
従来からベビーベッドにも各種のものがあり、赤ちゃんのいる多くの家庭で使用されている。例えば従来のベビーベッドは、前枠を上部前枠と下部前枠（開閉扉）とに分離形成し、上部前枠を左右の両側枠の前側縦枠部材に沿って上下方向に移動でき、かつ、上部前枠を所定箇所で係止具によって前側縦枠部材に固定し、ベビーベッドの前側上部を、上部前枠で閉じたり開けたりできるようにしてあった。
【０００３】
上記の係止具による上部前枠と前側縦枠部材との従来の係止構造を図８を参照してさらに詳述すると、従来のベビーベッド（図示省略）の左右の側枠の前側縦枠部材１０１には、所定箇所（例えば上端部近傍）に、両側方向に一端閉塞孔１０２が形成され、一方、上部前枠１０３によってベビーベッドの前側上部を閉じた時に、上記の一端閉塞孔１０２と合致する上部前枠１０３の縦枠部１０４の位置には、係止具１０５を挿通できる挿通孔１０６が形成されている。この挿通孔１０６は大径筒部１０７と小径筒部１０８とからなる。
【０００４】
また、図示の係止具１０５は、大径軸部１０９と小径軸部１１０と係止キャップ１１１及びバネ１１２とからなるものであった。
【０００５】
この係止具１０５を上部前枠１０３の縦枠部１０４に取り付ける場合は、係止具１０５の小径軸部１１０にバネ１１２を装着し、小径軸部１１０を縦枠部１０４の大径筒部１０７から小径筒部１０８側に挿通し、小径筒部１０８から突出した小径軸部１１０に係止キャップ１１１を取り付ける。
【０００６】
そして前枠１０３によってベビーベッドの前側上部を開ける場合は、係止キャップ１１１を摘みバネ１１２の弾発付勢に抗して側方に引き、係止具１０５の大径軸部１０９を縦枠部１０４の大径筒部１０７に収納して、大径軸部１０９による前枠１０３と側枠の前側縦枠部材１０１との係止関係を解除し、前枠１０３を下方に移動させたり、前方に倒したりしてベビーベッドの前側上部を開放していた。
【０００７】
また、前枠１０３によってベビーベッドの前側上部を閉じる場合は、係止キャップ１１１を摘みバネ１１２の弾発付勢に抗して側方に引っ張った状態で、前枠１０３を上方に移動させたり、前方に倒していた前枠１０３を元の状態に戻し、前側縦枠部材１０１の一端閉塞孔１０２と、前枠１０３の挿通孔１０６とを合致させた後に引っ張っていた係止キャップ１１１を離すことにより、バネ１１２の弾発付勢によって大径軸部１０９が前側縦枠部材１０１の一端閉塞孔１０２に挿入して、前側縦枠部材１０１に前枠１０３を固定し、前枠１０３によってベビーベッドの前側上部を閉じた状態に保持することができるようにしてあった。
【０００８】
【発明が解決しようとする課題】
ところが、上記のような従来の係止具１０５による前枠１０３と側枠の前側縦枠部材１０１との係止構造では、ベビーベッドの中に入れた赤ちゃんが前枠１０３や側枠を揺すったり、係止キャップ１１１を摘んで側方に引っ張ったりした時、係止関係が解除されて前枠１０３が開放してしまうといった懸念があり、安全上の観点から従来の係止構造及び係止具１０５の構造では問題であった。
【０００９】
そこで、このような問題に鑑みて開発されたのが本発明であり、その目的とするところは、赤ちゃんが簡単に前枠を開閉できないようにして、安全に赤ちゃんをベビーベッド内に入れておくことができるベビーベッドにおける前枠の係止構造及び係止具を提供することにある。
【００１０】
【課題を解決するための手段】
そこで、本発明は上記目的を有効に達成するために、次のような構成にしてある。すなわち、請求項１記載の本発明のベビーベッドにおける前枠の係止構造は、後枠と左右の側枠とをコ字状に接続するとともに、この左右の側枠の前側縦枠部材に前枠を上下方向に移動可能に、又は前後方向に開閉可能に取り付けて、上記の後枠と左右の側枠及び前枠からなる囲繞枠を形成し、かつ、囲繞枠の内側にベッド床部材を取り付け、さらに、上記前枠を係止具によって前側縦枠部材に着脱自在に係止できるようにしたベビーベッドにおいて、係止片部を設けた係止軸を備えた係止具を前枠の所定箇所に取り付け、かつ、上記の係止片部を挿入できる貫通孔を左右の側枠の前側縦枠部材に形成するとともに貫通孔内の下部側に凹部を形成し、前枠に取り付けた係止具の係止片部を係止軸とともに前側縦枠部材の貫通孔に挿入し、かつ、前枠とともに係止具を下げて、前側縦枠部材の貫通孔内の凹部に上記の係止片部を係止できるようにしたことを特徴とする構成にしてある。
【００１１】
請求項２記載の本発明のベビーベッドにおける前枠の係止構造は、後枠と左右の側枠とをコ字状に接続するとともに、この左右の側枠の前側縦枠部材に前枠を上下方向に移動可能に、又は前後方向に開閉可能に取り付けて、上記の後枠と左右の側枠及び前枠からなる囲繞枠を形成し、かつ、囲繞枠の内側にベッド床部材を取り付け、さらに、上記前枠を係止具によって前側縦枠部材に着脱自在に係止できるようにしたベビーベッドにおいて、上記の係止具は先端部に係止片部を有する大径軸部と小径軸部とを一体的に形成した係止軸と、この係止軸の小径軸部に装着するバネと、小径軸部の一端部に取り付ける係止キャップとからなり、上記の前側縦枠部材の所定箇所に、係止具の大径軸部を係止片部とともに挿通できる貫通孔を前側縦枠部材の両側方向に形成し、かつ、この貫通孔と連通し上記係止片部を係止できる凹部を前側縦枠部材の貫通孔内の下部側に形成し、さらに、上記のバネとともに係止具の大径軸部を収納できる大径筒部と、この大径筒部と連通し係止具の小径軸部を貫通できる小径筒部とからなる挿通孔を、前枠の縦枠部の所定箇所に形成し、上記の小径軸部にバネを装着した係止軸を、前枠の大径筒部側から挿入して小径軸部を小径筒部から前枠の内側方向に突出させ、さらに、この突出した小径軸部に係止キャップを取り付けて、係止具を前枠に取り付け、前枠の前側縦枠部材への固定時に、前側縦枠部材の貫通孔と前枠の挿通孔とを合致させて、前枠の挿通孔側から係止具の大径軸部を係止片部側から前側縦枠部材の貫通孔に挿入し、前枠の自重によって前枠とともに係止具の係止軸を降下させて係止片部を上記貫通孔内の凹部に係止して前枠を前側縦枠部材に固定し、
また、上記の固定した前枠を上下方向又は前後方向への移動時に、係止具を前枠とともに一旦上昇させて係止片部と凹部との係止関係を解除し、かつ、係止具の係止軸をバネの弾発付勢に抗して前枠側に移動させて、係止具による前枠と前側縦枠部材との係止関係を解除し、前枠を上下方向又は前後方向へ移動できるようにした構成を特徴とする構成にしてある。
【００１２】
請求項３記載の本発明の係止具は、先端部に係止片部を形成した大径軸部と、この大径軸部の他端に一体的に形成した小径軸部とからなる係止軸と、この係止軸の小径軸部に装着するバネと、小径軸部の一端部に取り付ける係止キャップとからなる構成である。
【００１３】
【発明の実施の形態】
以下、本発明の実施の形態について図１〜図７に基づいて説明する。
本発明のベビーベッド１は、後枠２、左右の側枠３、４及び前枠５によって構成される囲繞枠６と、この囲繞枠６の内側に取り付けるベッド床部材７等からなる。
【００１４】
上記の前枠５は、ベビーベッド１の前側上部を被うことができるものであり、左右の側枠３、４の前側縦枠部材８、９に沿って上下方向に移動できるように、両前側縦枠部材８、９に取り付けてある。
【００１５】
すなわち、前枠５には、四隅の外側部に係合凸部１０（図５参照）が設けられ、この係合凸部１０は左右の側枠３、４の前側縦枠部材８、９（図４参照）の内面側に形成した縦溝１１（左の側枠３の縦溝は側枠４の縦溝１１と対峙する位置に形成されており図示省略する）に移動可能に係合できるようにしてある。
【００１６】
また、前枠５は、左右の側枠３、４の前側縦枠部材８、９に係止具１２を介して着脱自在に係止できるようにしてある。
【００１７】
この係止具１２は、図２、図３に示すように先端部に係止片部１３を形成した大径軸部１４と、この大径軸部１４の他端に一体的に形成した小径軸部１５とからなる係止軸１６と、この係止軸１６の小径軸部１５に装着するバネ１７と、小径軸部１５の一端に取り付ける係止キャップ１８とからなる。小径軸部１５の一端部は雄ねじ部１９ａを形成してあり、係止キャップ１８に形成した雌ねじ部１９ｂ（図５参照）と螺合させて、雄ねじ部１９ａに係止キャップ１８を取り付けできるようにしてある。大径軸部１４は小径軸部１５より短く形成してある。また、係止片部１３は、角を丸くした矩形状の小片板であって大径軸部１４の端面形状より大きく、大径軸部１４の端面に固着し、大径軸部１４から半径方向に突出している。勿論、係止片部１３は大径軸部１４と一体的に形成してもよい。
【００１８】
前枠５（図５〜図７参照）の上端側の係合凸部１０の近傍の縦枠部２０には、係止具１２の係止軸１６を挿通できる挿通孔２１が形成されている。挿通孔２１は、バネ１７並びに係止具１２の大径軸部１４を収納できる大径筒部２２と、この大径筒部２２と連通し係止具１２の小径軸部１５を貫通できる小径筒部２３とからなる。大径筒部２２は、前枠５の縦枠部２０の外側端から内側に形成され、さらに大径筒部２２と連通する小径筒部２３が前枠５の縦枠部２０の内側端まで形成されている。
【００１９】
上記の係止具１２は、前枠５の挿通孔２１に取り付けられている。すなわち、係止具１２の小径軸部１５にバネ１７を装着した係止軸１６を、前枠５の大径筒部２２側から挿入して小径軸部１５を前枠５の小径筒部２３から前枠５の内側方向に突出させ、さらに、この突出した小径軸部１５の雄ねじ部１９ａに係止キャップ１８を取り付けて、係止具１２を前枠５に取り付けてある。
【００２０】
大径軸部１４は、バネ１７の弾発付勢により通常は大径筒部２２から外方（側方）に突出している（図６参照）。
【００２１】
一方、前枠５によってベビーベッド１の前側上部を被う（閉じる）場合には（図１参照）、前枠５を縦溝１１に沿ってベッド床部材７より上に移動させる。この場合、前枠５（図６参照）の挿通孔２１と対峙する左右の側枠３、４の前側縦枠部材８、９に、貫通孔２４が両側方向に形成されている。尚、この貫通孔２４は、側枠３、４の外面側を封鎖した一端閉塞孔に設計変更してもよい。
【００２２】
この貫通孔２４は、係止具１２の大径軸部１４を係止片部１３とともに挿通でき、かつ、上記係止片部１３を係止できる凹部２５が、貫通孔２４と連通するようにして貫通孔２４の下部で前側縦枠部材８、９の外側端側に形成されている。
【００２３】
本発明のベビーベッド１における前枠５の係止構造は、上述のように構成されていて、前枠５を左右の側枠３、４の前側縦枠部材８、９に固定する場合は、
係止キャップ１８を引いて係止具１２の大径軸部１４を前枠５の大径筒部２２内に収納しながら（図５参照）、前側縦枠部材８、９の貫通孔２４（片側図示せず）と前枠５の挿通孔２１（片側図示せず）との合致する位置に前枠５を移動させる。
【００２４】
そして図６に示すように前側縦枠部材８、９の貫通孔２４（片側図示せず）と前枠５の挿通孔２１（片側図示せず）とが合致した位置で係止キャップ１８を離すことにより、係止軸１６はバネ１７の弾発付勢によって前側縦枠部材８、９の貫通孔２４内に挿入していき、係止具１２の係止片部１３は貫通孔２４内の凹部２５に位置する。このようにした後に人手によって支えていた前枠５を離すことにより、前枠５の自重によって前枠５は下がり、係止具１２の係止片部１３は上記の凹部２５に係止することになる。このようにして前枠５を左右の側枠３、４の前側縦枠部材８、９に固定することができる。
【００２５】
また、前枠５を開放しようとすれば、一旦、前枠５を少し持ち上げて係止具１２の係止片部１３と前側縦枠部材８、９の凹部２５との係止関係を解除するとともに、係止キャップ１８を引いて係止具１２の大径軸部１４を前枠５の大径筒部２２内に収納しなければ、前枠５と前側縦枠部材８、９との固定状態を解除することがでなきないため、赤ちゃんが係止キャップ１８をいじったり、前枠５を揺すったりしても、簡単に前枠５が開放してしまうといったことがない。
【００２６】
さらに、赤ちゃんが左右の側枠３、４を揺すっても、従来であれば図８に示したように係止具１０５の大径軸部１０９が前側縦枠部材１０１の一端閉塞孔１０２に係止していたため、大径軸部１０９が一端閉塞孔１０２から抜けて前枠５を開放してしまうといった懸念があったが、本発明では凹部２５に係止具１２の係止片部１３が嵌まり込んで係止するようにしてあるので、左右の側枠３、４を揺すっても前枠５が開放してしまうといったことがない。
【００２７】
なお、左右の側枠３、４の前側縦枠部材８、９の縦溝１１内（図４参照）には、貫通孔２４より下方に所定間隔を以て係合凹部２６が形成されていて、この係合凹部２６に係止具１２の係止片部１３を係合させることによって、上下移動可能な前枠５を各係合凹部２６の位置でも係止することができる。
【００２８】
【発明の効果】
このように本発明のベビーベッドにおける前枠の係止構造では、ベビーベッドの前面側を被う前枠を開放する場合には、一旦前枠を持ち上げて、前枠の左右に取り付けた係止具の係止片部を、左右の側枠の前側縦枠部材の貫通孔に形成した凹部から外さないと、前枠と側枠との係止関係を解除することができないため、赤ちゃんが前枠や側枠を揺すったり、係止具を引っ張ったりしても、容易に前枠が開くといったこともなく、安心して赤ちゃんをベビーベッド内に入れておくことができる。
【００２９】
また、本発明の係止具は、係止軸の先端部に係止片部を有しているので、この係止片部を連結対象物の凹部に係止することより、係止軸の長手方向に簡単に抜けるのを防止することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a crib.
[0002]
[Prior art]
Conventionally, there are various types of baby beds, and they are used in many homes where babies are present. For example, a conventional crib has a front frame separated into an upper front frame and a lower front frame (opening / closing door), the upper front frame can be moved vertically along the front vertical frame members of the left and right side frames, and The upper front frame is fixed to the front vertical frame member by a locking device at a predetermined position so that the front upper portion of the crib can be closed or opened by the upper front frame.
[0003]
The conventional locking structure between the upper front frame and the front vertical frame member by the above-described locking tool will be described in more detail with reference to FIG. 8. The front vertical frames of the left and right side frames of the conventional baby bed (not shown) In the member 101, one end closing hole 102 is formed in both sides at a predetermined location (for example, near the upper end). On the other hand, when the upper front frame 103 is closed by the upper front frame 103, An insertion hole 106 through which the locking tool 105 can be inserted is formed at the position of the vertical frame portion 104 of the matching upper front frame 103. The insertion hole 106 includes a large diameter cylindrical portion 107 and a small diameter cylindrical portion 108.
[0004]
The illustrated locking tool 105 includes a large-diameter shaft portion 109, a small-diameter shaft portion 110, a locking cap 111, and a spring 112.
[0005]
When attaching the locking tool 105 to the vertical frame portion 104 of the upper front frame 103, a spring 112 is attached to the small diameter shaft portion 110 of the locking tool 105, and the small diameter shaft portion 110 is attached to the large diameter cylindrical portion of the vertical frame portion 104. The locking cap 111 is attached to the small-diameter shaft part 110 that is inserted from the small-diameter cylinder part 108 through the small-diameter cylinder part 108.
[0006]
When the front upper portion of the crib is opened by the front frame 103, the locking cap 111 is picked and pulled sideways against the elastic biasing force of the spring 112, and the large-diameter shaft portion 109 of the locking tool 105 is moved to the vertical frame. Stored in the large-diameter cylindrical portion 107 of the portion 104, the locking relationship between the front frame 103 and the front vertical frame member 101 of the side frame by the large-diameter shaft portion 109 is released, and the front frame 103 is moved downward, The front upper part of the crib was opened by knocking forward.
[0007]
Further, when closing the front upper part of the crib with the front frame 103, the front frame 103 is moved upward in a state where the locking cap 111 is picked and pulled sideways against the elastic biasing force of the spring 112. The front frame 103 that has been tilted forward is returned to its original state, and the locking cap 111 that has been pulled is released after the one end blocking hole 102 of the front vertical frame member 101 is aligned with the insertion hole 106 of the front frame 103. Thus, the large-diameter shaft portion 109 is inserted into the one end closing hole 102 of the front vertical frame member 101 by the elastic urging force of the spring 112, and the front frame 103 is fixed to the front vertical frame member 101. The front upper part of the bed could be kept closed.
[0008]
[Problems to be solved by the invention]
However, in the locking structure of the front frame 103 and the front vertical frame member 101 of the side frame by the conventional locking tool 105 as described above, a baby put in the crib shakes the front frame 103 or the side frame. When the locking cap 111 is picked and pulled to the side, there is a concern that the locking relationship is released and the front frame 103 is opened. The structure of 105 was a problem.

Further, even if the baby rocks the left and right side frames 3 and 4, conventionally, the large-diameter shaft portion 109 of the locking tool 105 is engaged with the one end closing hole 102 of the front vertical frame member 101 as shown in FIG. However, in the present invention, the locking piece portion 13 of the locking tool 12 is disposed in the recess 25 in the present invention. Since they are fitted and locked, the front frame 5 does not open even if the left and right side frames 3 and 4 are shaken.
[0027]
In the vertical grooves 11 of the front vertical frame members 8 and 9 of the left and right side frames 3 and 4 (see FIG. 4), engaging recesses 26 are formed below the through holes 24 with a predetermined interval. By engaging the engagement piece portion 13 of the engagement tool 12 with the engagement recess portion 26, the front frame 5 that can move up and down can be also locked at the position of each engagement recess portion 26.
[0028]
【The invention's effect】
As described above, in the front frame locking structure in the crib of the present invention, when the front frame covering the front side of the crib is opened, the front frame is once lifted and attached to the left and right of the front frame. Since the locking relationship between the front frame and the side frame cannot be released unless the locking pieces of the tool are removed from the recesses formed in the through holes of the front vertical frame members of the left and right side frames, Even if the frame or side frame is shaken or the locking member is pulled, the front frame does not open easily, and the baby can be safely put in the crib.
[0029]
In addition, since the locking tool of the present invention has the locking piece at the tip of the locking shaft, the locking piece is locked to the recess of the connection object by locking the locking piece. It is possible to prevent it from easily coming off in the longitudinal direction.
